CASEMENT-WINDOW ADJUSTER.

Application filed November 13, 1928. Serial No. 319,079.

The present invention relates to improvements in closure fasteners and has for its principal object to provide a simple and efficient device for association with a swinging window whereby the same may be held socure in any open position so that rattling or accidental closing of the window will be prevented. I

Another important object of the invention is to provide a closure fastener of the above mentioned character that will at all times be positive and eliicient in its operation, the same being further of such construction as to permit the same to be readily and easily installed on a window without necessitating any alterations.

Still a further object is to provide a casement adjuster of the above mentioned character which is simple in construction, ineXpensive strong and durable and further well adapted to the purpose for which it is designed.

Other objects and advantages of the invention will become apparent from the following description when "taken in connection with the accompanaying drawings.

In the accompanaying drawings wherein like reference characters indicate corresponding parts throughout the same:

Figure 1 is a top plan view of the easement adjuster embodying my invention. showing the manner in which the same is used to secure a vertically swinging window sash in a partially onened position.

Figure 2 is a side elevation. thereof.

Figure 3 is an enlarged fragmentary top plan view of the adjacent ends of the tubing and the slidable rods showing the spring actuated locking device associated with the nection between the outer end of the rod and the bracket that is secured to the vertically swinging window sash.

Figure 7 is a detail perspective view of the bracket for attaching the tubular member to J the window sill. p I I Figure 8 is a similar view of the bracket for attaching the rod to the window sash.

Figure 9 is a perspective view ofthe cast ing forming a part of the locking device.

Figure 10 is a fragmentary perspective view ofthe tubular member forming a salient part of the present invention.

Figure 11 is a detail perspective view of the cap that is secured on the outer end of the tubular member.

Figure 12 is a view similar to Figure 10 illustrating the slidable rod, and

i igure 13 is a detail perspective view of one of the levers forming a part of the locking device. I

In the drawings whereinfor the purpose of illustration is shown the preferred embodiment of my invention the numeral lrlesignates generally my improved casement adt juster, the same comprising an elongated tubular member 2 that is open at its outer end. The inner end of this'tubular member is formed with an inwardly directed flange 5, the purpose of which will be presently apparent. s

Furthermore the inner end portion of the tubular member is externally, threaded as illustrated at .4, with reference moreparticu" larly to Figures 4 and 10 of the drawings.

A cap 5 is removably fitted over the outer open end of the tubular member 2, and this formed in the lower end portion of the headed pin for disposition against the bottom face of the raised central portion 7 of the bracket through the flanged inner end of the tubular member 2 and a head 12 is formed on the inner end of the rod 11 for disposition'within the tubular member 2, said head 12 cooperating with the flange 3 toprevent the disengagement of the rod from the tubular member.

This detail is more clearly disclosed in Figure 4 or the drawings.

A bracket designated generally by the nu meral 13 is formed with a pair of parallel spaced laterally extending apertured lugs 14, and this bracket is rigidly secured to the inher face of the swinging window sash C adj acent the lower edge thereof. The outer end of the rod 11 is-pivotally secured between the laterally extending ears 1 through the me dium of the pin 15 that extends through the openings formed in the outer end portions of said ears, and which pin further projects transversely through the outer end portion of the rod 11, in the manner .as more clearly suggested in Figure 6.

At the meeting ends ofthetubular member 2 and the rod 11, there is arranged the locking devices denoted generally by the reference character 16. This locln'ng device includes a casting 17 that is formed with an enlarged cavity 18in the bottom thereof, the central portion of the cavity benig wider than the end portions so as to form the shoulders 19 and 20, respectively, as more clearly shown in Figure 9,?and the purpose thereof will be presently described. The top of the casting 17 is formed with a rectangular shaped opening 21 that has communication with the cavity 18. The inner end of the casting is formed with a threaded bore 22 that communicates with the adjacent end of the cavity 18'and the threaded inner ends of the casting is secured on the threaded inner end of the tubular member 2, as indicated in Figure4 whereby said casting is rigidly secured on the inner end of the tubular member, and the outer end of the casting is formed with an opening 23 that is arranged in alinement with the opening 22 to permit the free sliding movement of the rod 11 therethrough.

A pair ofplate like levers 2d and 25extend downwardly into the cavity 18 through the opening 21 iiormed in thetop of the casting, the upper'endsof these levers forming handles. The lower ends of the levers are formed with holes such as shown at 26 in Figure 13 which are slightly larger than the diameter of the rod 11, and the rod extends through these holes in-the lower ends of the levers.

Suitable expansible coil springs 27 encircle the rod 11 within the casting l7, and as s clearly shown in Figure a l, one of these coil springs is disposed between the outer side face of the lever 24, and the inner end of the tubularv member 2, while the other end of the coil spring is disposed between the outer side face of the complementary lever 25, and the adjacent end of the castin These springs normally hold the lower ends of the levers away from the shoulders 19 and 20, respectively, so as to-dispose the levers at an angle whereby to aiiord a clamping action of the sides of the hole-through the levers 24 and 25 against the rod 11 when under the influence of the coil springs 27, and when' the parts are arranged in this position, the rod 11 cannot move with respect to the tubular member 2, thus the window sash C may be locked in any open adjusted position.

he-never it is desired to swing the window sash, the operator grasps the outer or upper ends of the levers 24 and 25, and pushes said levers toward each other so that the same assumes a vertical position and whereby the lower ends of the levers will abut against the shoulders 19 and 20, thus permitting the free movement of the rod 11 through the holes 26.

In this way, the vertically swinging window sash may be secured in any open adjusted position against rattling and further against being accidentally shut.

The simplicity-or my improved casement adjuster enables the same to be readily and easily installed, and the device will at all times be positive and eilicient'in carrying out the purposes for which it is designed; 7

While I have shown the preferred embodiment of myinvention it is to be understood that minor changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention, and'the scope of the appended claims.

Having thus described. the invention, what I claim as new and desire to secure by Letters Patent is i v 1 1. Ina window fastener, a tubular member having its inner end formed with an inwardly directed flange, means for pivotally securing the outer end of the tubular member, to a window casing, a rod pivotally secured at its outer end to a swinging window mounted in the casing, the inner end of the rod being slidable within the'inne'r end of the tubular member, a head formed on the inner end of the rod for engagement withthe flange to preventthe displacement ofthe rod from the tubular member, a locking device associated inn with the adjacent end of the tubular member and the slidable rod for securing the window 1n openposition of ad ustment, said locking device lncludmg a casing secured atone end on the inner endof thetubular member, the

other end of the casing being formedqwith an openingthrough'which said rod is slidable,

the top of the casing being formed with an opening, a pair of opposed levers extending downwardly through the opening in the top of the casing, the lower ends of the levers being formed with registering openings of a diameter slightly greater than that of the rod and through which said rod is disposed, and coil springs encircling the rod and disposed between the outer side faces of the lower end portions of the levers and the adjacent ends of the casing for normally holding said levers in a canted position to cause a clamping action on the rod and prevent casual sliding movement thereof.

2. In a window fastener, a tubular member having its inner end formed with an inwardly directed flange, means for pivotally securing the outer end of the tubular member to a window casing, a rod pivotally secured at its outer end'to a swinging window mounted in the casing, the inner end of the rod being slidable within the inner end of the tubular member, a head formed on the inner end of the rod "for engagement with the flange to prevent the displacement of the rod from the tubular member, a locking device associated with the adjacent end of the tubular member and the slidable rod for securing the window in open position of adjustment, said locking device including a casing secured at one end on the inner end of the tubular member, the other end of the casing being formed with an opening through which said rod is slidable, the top of the casing being formed with an opening, a pair of opposed levers extending downwardly through the opening in the top of the casing, the lower ends of the levers being formed with registering openings of a diameter slightly greater than that of the rod and through which said rod is disposed, and coil springs encircling the rod and disposed between the outer side faces of the lower end portions of the levers and the adjacent ends of the casing for normally holding said levers in a canted position to cause a clamping action on the rod and prevent casual sliding movement thereof, and stop forming members arranged within the casing at predetermined points for cooperation with the lower ends of the levers whereby the rod can be free to slide through the casing when the levers are disposed against the shoulders.

In testimony whereof I affix my signature.
